Where the K value is 3.2 x 10-6?
A 250.0-mg sample of an organic weak acid is dissolved in an appropriate solvent and titrated with 0.0556 M NaOH, requiring 32.58 mL to reach the end point. Determine the compound’s equivalent weight.
how to prepare a 5moldm-3 HCl solution from 12moldm-3 and 2moldm-3 HCl solution
at standard temperature and pressure one mole of gas occupies a volume on 22.415dm³ , exert a pressure of one atmosphere at 0°c . Calculate the molar gas constant
How the Ca2+ can be analyzed if its reduced form does not have any selective indicator
A 11.3 sample of CaCO3 was treated with aqueous H2SO4, producing calcium sulfate, water and 3.65 g of CO2(g). What was the % yield of CO2?
The density of air at 20°C and 1 atm is 1.205g/L. If this air were compressed at the same temperature to equal the pressure at 40.0m below sea level, what would b it's density? Assume the barometric pressure is constant at 1 atm . The density of sea water is 1.025g/cm³
Prepare a desighn qualification report for purchasing the glass marking pencils for laboratory
The student has two solutions separated by a semipermeable membrane that only allows water to pass through it. The right side of the membrane has 3.0 moles of compound A (MW = 350 g/mol), and the left side has 2.0 moles of compound B (MW 150 g/mol). What do you think will happen to the solution? Rise on the right, rise on the left, or remain at a matching level on both sides?
Phytonadione, or more known as vitamin K1 , serves important roles in blood clotting mechanisms, bone health, and even bone health. When 0.368 g is dissolved in 12.0 g of camphor, the freezing point is lowered by 2.45 °C.
